EI - You're still beating me in the number of posts count though :grin:

With your point on the home TAB it pays to remember that Supertab is really the "home" TAB for races in Vic, WA, Tas & ACT. Unitab is "home" for SA, Qld & NT. With Supertab the way the odds are worked out is:
1. Tabcorp computer sends request to other TAB's computers for a "collation update"
2. Other TABs computers send the collation totals (total value of win and place bets on each horse and value of Quinella bets on each combination) to TABCORP
3. TABCORP computer adds these collations to their own totals then calculates the odds for each runner.
4. Odds are released to Agencies, SKY, Teletext, Website (eventually!), etc, and also sent back to the Other TABS who then must update their own displays, websites, etc.

This all takes a little time so probably explains why Supertab is slower than the others at doing these updates.
